Bitcoin is safe, it will always be that way. This type of fluctuations is nothing new in the stock markets game. Think Bitcoin, think Gold. Is just the same.
Anyway, I will rather focus my attention on the protocol itself, and try to find what can be created on top of it :).
It's a big difference between Gold and BTC, Gold it's material(the best nonmetal) and very rare, BTC it's virtual and volatile (POW( electricity)), electricity it's very volatile. Conclusion gold it's palpable, BTC it's not palpable. :)
As long as we keep converting resources to mine Bitcoin, the value it will only increase. Gold is useless deep down in the earth, it has to be mined to get his value. Bitcoin is as volatile as the internet is. Would you believe me that, if the internet get to crash, gold will have the equal value of bitcoin, close to none?
For many, many years after;). Bitcoin is the same as Gold when we talk about store value, not currency to buy commodities. For that, we have thousands of alt-coins :).
Maybe it's is in one way but not only bitcoin, are there altcoin better then bitcoin
